Motor Cortex Controls Humans’ Decisions

14-Oct-2016

The scientists have revealed that human decisions are controlled by the brain. As per the study the scientists have found the evidence that challenges the traditional belief. Traditionally it is believed that the motor cortex functions the response mechanism without affecting the choice itself.

According to the scientists the new study challenges the instinctive division between a 'deciding' and a 'responding' stage in choice making. A test was first conducted on humans by the scientists. Through the test the scientists has cleared that brains could not map a motor response while forming a choice.

The findings have suggested that the motor cortex also plays an important role in informing decision-based behavior. The researchers have observed that there is a neural correlation of the choice tendency in the motor cortex. Imminent motor decision can be foretold from the position of motor areas even before decision formation has begun stated the scientists.
